Researchers ‘Print’ Polymers That Bend Into 3-D Shapes

March 11, 2012 – 3:00 am

Researchers 'Print' Polymers That Bend Into 3-D Shapes - Christian Santangelo, Ryan Hayward and colleagues at the University of Massachusetts Amherst recently employed photographic techniques and polymer science to develop a new technique for printing two-dimensional sheets of polymers that can fold into three-dimensional shapes when water is added. The technique may lead to wide ranging practical applications from medicine to robotics. The researchers' work is described in the March 9, 2012 issue of the journal Science.

Magnetic Yeast

March 2, 2012 – 12:00 pm

Magnetic Yeast - Yeast cells aren’t normally magnetic, but a little genetic engineering can make them thralls to a magnetic field. The research, published in PLoS Biology, suggests that manipulations of a few widely expressed genes could be enough to get any cell magnetized, which could be a powerful tool for both research and medicine. Original reference: K. Nishida and P.A. Silver, “Induction of Biogenic Magnetization and Redox Control by a Component of the Target of Rapamycin Complex 1 Signaling Pathway,” PLoS Biology, doi:10.1371/journal.pbio.1001269, 2012.

Cyclotron remedy for imaging isotope shortages

February 26, 2012 – 10:00 pm
  • Cyclotron remedy for imaging isotope shortages - A breakthrough in cyclotron technology is set to end shortages of a vital medical imaging isotope. The new technology will result in the decentralisation of the production of technetium-99m, with hospitals making the isotope on demand using tabletop cyclotrons.
